A centrifugal classifier including a classifier housing having at least one coarse material outlet and a classifier wheel, revolving in the classifier housing. The classifier wheel is comprised of a classifier drum and a classifier wheel shaft forming the axis of rotation of the classifier drum. A guide member is arranged near the coarse material outlet, at a set distance from the inner jacket surface of the classifier housing section surrounding the classifier drum. The guide member is configured such that classifying material flowing along the inner jacket surface at a radial distance less than or equal to the set distance circumvents the guide member and is discharged into the coarse material outlet and classifying material flowing along the inner jacket surface at a radial distance greater than the set distance is deflected in a radially inward direction toward the classifying drum.
